6PPD Exposure and Effects Research at Columbia Environmental Research Center
N-(1,3-dimethylbutyl)-N' -phenyl-p-phenylenediamine or 6PPD is a chemical additive that protects tires from damage due to certain reactive oxygen species. 6PPD, when in contact with ozone, reacts to form the derivative 6PPD-quinone (6PPD-Q). As tires wear with time, this derivative is dispensed into the environment, travels through drainage systems when it rains and, eventually, finds its way into...
A National Assessment of Pesticide, PFAS, Microplastic, and Antibiotic Resistance Gene Exposures in White-Tailed Deer
Research has documented exposures and consequential environmental health effects of pesticides, PFAS, microplastics, and antibiotic resistance genes in environmental biota. Little is known, however, regarding such effects in white-tailed deer ( Odocoileus virginianus ).
Per- and Polyfluoroalkyl Substance Exposure and Effects Research at Columbia Environmental Research Center (CERC)
The Columbia Environmental Research Center’s Per- and Polyfluoroalkyl Substance (PFAS) team conducts research focusing on the occurrence, fate, and toxicity of PFAS compounds in aquatic and terrestrial systems. Laboratory capabilities include dedicated analytical instrumentation and experimental facilities to allow USGS scientists to analyze a wide range of sample types including water, sediment...
Southeast Region Fluorochemical Network (SERFN)
Fluorochemicals are a class of structurally diverse synthetic compounds that contain a carbon-fluorine backbone.
Costs and Benefits of Nitrapyrin
In December 2020, our research group (as part of the Food Integrated Science Team) published a review of nitrapyrin costs and benefits in the journal Environmental Science & Technology .
